Assembly box structure

ABSTRACT

An assembly box structure includes two first side boards and two second side boards. Symmetric protruding portions are outwardly extended from two short sides of the first side boards. Symmetric recession portions are inwardly caved at two sides of a longer edge of the second side board. The protruding portion of one side of the first side board is embedded with the recession portion of the second side board through the two first side boards interlaced and assembled to the two second side boards, thereby rapidly assembling the hollow box body. Side bottom boards are extended from the bottoms of the first and second side boards. A plurality of through holes is arranged according to the proper distance spaced at interval. A plurality of expansion cylinders is at the periphery of the bottom of a bottom board, and corresponds to the through holes of each side bottom board.

FIELD OF THE INVENTION

The present invention relates to a box structure, and more particularly to an assembly box structure.

BACKGROUND OF THE INVENTION

According to the publication information, an assembly board is divided into two board body set, wherein the first board body has the embedding portion composed of multiple bending form and the upper and lower bonding boards. The second board body also has the connection portion composed of multiple bending forms and the upper and lower engaging boards. The assembly board has the drawbacks of time consuming and complicated during the processing procedure.

Further, the first board body and the second board body are thin plates. The assembly manner may result in larger intervals and not fasten although the embedding portion and the connection portion can be fitted to each other.

Accordingly, to overcome the foregoing shortcomings, the inventor(s) of the present invention based on years of experience in the related field to conduct extensive researches and experiments, and finally invented an assembly box structure.

SUMMARY OF THE INVENTION

The objective of the present invention is to provide an assembly box structure having easy assembly and high structure strength.

To achieve the foregoing objective, the assembly box structure disclosed by the present invention includes two first side boards and two second side boards interlaced and embedded to each other. Symmetric protruding portions are outwardly extended from two short sides of the first side boards. The protruding portion is composed of an extending section and a width expansion section. In addition, a cover sheet is outwardly extended from the tops of the protruding portions. Symmetric recession portions are inwardly caved at two sides of a longer edge of the second side board. The recession portion is composed of a cross-section channel and a width expansion slot. The depth of the cross-section channel is slightly smaller than the length of the extending section. The depth of the width expansion slot is greater than the length of the width expansion section. The cover sheet can seal the upper opening of the width expansion slot. Accordingly, the contact area can be reduced while assembling the protruding portion and the recession portion. The width expansion slot can be closely covered by the cover sheet to achieve fast insertion and effect of close overlaying.

Other features and advantages of the present invention and variations thereof will become apparent from the following description, drawings, and claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

Please referring FIG. 1 to FIG. 4, schematic diagrams of an assembly box structure is shown according to a preferred embodiment of the present invention. The structure includes two first side boards 10 and two second side boards 20 having the same height and width. Both the first side boards and the second side boards are interlaced and embedded to each other.

Symmetric protruding portions 11 are outwardly extended from two short sides of the first side boards 11. The protruding portion 11 is composed of an extending section 12 and a width expansion section 13. Cover sheets 14 are outwardly extended from the tops of the protruding portions. A proper distance is remained between the bottom of the protruding portion 11 and the bottom of the first side board 10.

Symmetric recession portions 21 are inwardly caved at two sides from one of longer edges of the second side board 20. The recession portion 21 is composed of a cross-section channel 22 and a width expansion slot 23. The depth of the cross-section channel 22 is slightly smaller than the length of the extending section 12 of the first side board 10. The depth of the width expansion slot 23 is slightly greater than the length of the width expansion section 13 of the first side board 10. The cover sheet 14 of the first side board 10 can seal the upper opening of the width expansion slot 23 completely. In addition, the bottom of the recession portion 21 is the non-penetrating shape.

By utilizing the above components, when the protruding portion 11 of the first side board 10 is embedded to the recession portion 21 of the second side board 20 in order, the operation of smoothly performing the embedding effect can be acquired during the initial stage. The cover sheet 14 then is used to completely and closely seal the opening of the width expansion slot 23 during the subsequent stage to achieve effects of rapid embedding and close fitting, thereby assembling the hollow box body 100.

As shown in FIG. 5, a reference diagram of an assembly box structure is shown according to the present invention. A plurality of box bodies 100 are stacked up with each other to arrange the multiplayer type rack at will.

Moreover, referring FIG. 6 to FIG. 8, schematic diagrams of the assembly box structure is shown according to a preferred embodiment II of the preset invention. In the box body 100 interlaced by two first side boards 10 and two second side boards 20, side bottom boards 15 and 25 are extended from the inner bottoms of the first side board 10 and the second side board 20. A plurality of through holes 151 and 251 is arranged to each side bottom board 15 and 25 based on the proper distance spaced at interval. A plurality of expansion cylinders 31 is further at the periphery of the bottom of a bottom board, and corresponds to the through holes 151 and 251 of each side bottom board 15 and 25. Accordingly, the bottom sealed box 110 can be assembled.

Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to persons skilled in the art. It is, therefore, contemplated that the appended claims will cover all modifications that fall within the true scope of the invention.
